ORCHARD AND VlNEYARD CULTiv'ATOR.

SPECIFICATION forming part of Letters Patent; No. 387,765, dated August 1 1-, 1388.

Application filed April 18H.

T (l-ZZ whom, it may concern.-

Be it known that I, GUY \VA'RD (iatiri-nngr, of San Jose, Santa Clara county, State of California, have invented an Improvement in Orchard and Vineyard Cultivators; andlhereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of cultivators specially adapted for use in orchards and vineyards; and my invention consists in a shifting or adjustable tongue or pole, its ar rangeinent and mechanism for operating it; in an adjustable seat and its arrangement; in attachable and detachable side teeth and the manner of connecting and disconnecting them; in the novel construction and arrangement of the frame; in the peculiar huh or dust cap or cover and scrapersnpport, and in details of construction, all of which, together with the objects of the several improvements, I shall hereinafter fully describe by reference to the accompanying drawings, in which--- Figure 1 is a perspective view of my cultivator. 2 is a horizontal section of the hub or dust cap or cover, showing its application to the wheel-hub and its support of the scraper. Fig. 3 is a, vertical longitudinal section through the front cl'ossplate, a, of the frame, showing the pivoting 0f brackets B.

A. is the frame generally. This consists of longitudinal parallel body-bars a, the double cross-plates a. between which the rear ends of bars c are bolted, and the parallel back bars, a, lying outside of the planes of the bodybars and within the planes of the ends of the cross-plates. The bod y-bars and the back bars are made of channel-iron. The bars a are connected about their centers by the cross-plate a" and near their forward ends by the double crossplates a. To the upper one of these cross'plates n is pivoted by the pin or bolt b the bracket in which the pole or tongue G is connected by the cross-bolt c. The tongue extends rearwardly to the back of the frame, and has pivoted on its extreme rear end the lever I), the lower end of which is forked and bears against the fixed fulcrum-pin (Z, extending from the lower cross-plate, a.

E is a rack, which is fixed on top of the rear end of the tongue or pole and with which the lever l) engages. On the upper cross Serial No. 272,275. (No model.)

plate, a, is fixed a gnidcrail, F, in which a bent guide-arm, c, on the tongue or pole 0 plays. It will now be seen that by moving the lover I) it swings or shifts the tongue or 5 pole about the pivotb to one side or the other. The object of this is to get the horses away from the vines and trees and still allow the machine to work up as close to them as possible. Another advantage of this shifting or swinging tongue is that when the machine is working on the hillside the tendency to work downhill may be counteracted by throwing the tongue to one side, so as to direct the wheels slightly against the slope of the hill.

G are the wheels of the machine connected with the main frame in any suitable manner.

H is a bracket firmly secured on the tongue or pole over the axial center of the machine. The top of this bracket is provided with a lon- 7o gitndinal slot, g, in which plays the threaded pin it on the spring-support h of the seat if. A thumb-nut, h, is fitted on the threaded pin and serves to hold the seat in the position to which it is set. This construction enablesthe 7 5 seat H to be set forward or back to oneiside or the other of the axial center of the machine, the object being to transfer the weight backwardly upon the teeth when the machine is at work and forwardly when not at work.

I are the ordinary teeth of the cultivator, having suitable standards secured to the frame.

J are supplementary side teeth to be at tached to the frame when the width of the machine is to be increased, according to the 8 work desired, whether in orchard or in vineyard. These teeth J have outwardly-extol]ded bent standards j, and they are secured to the frame by passing into a grooved casting, K, which is bolted between the ends of the crossgo plates at of the main frame, and said standards are secured in this position by means of setscrews 75. These castings hold these teeth firmly and provide for their ready removal or replacement by taking out or puttingin the setscrews. By these removable teeth the machine may be adapted for wider work, according to the place in which it is used and to the necessities of the case, thus rendering the machine practical in both orchard and vineyard.

L is a casting, one end of which is socketed and fixed over the inner end of the hub of the wheel; the other end is extended, and to it is bolted the lower end of the wheel-scraper N. This casting therefor forms a combined dust cover or cap for the hub and support for the scraper.

The arrangement of the frame, as described, is of a simple nature, and yet of a character enabling the teeth to be set in the proper positions for working.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, 1's- 1. In an orchard and Vineyard cultivator, the combination of the frame and the supplementary teeth having bent standards extended to one side and adapted to be fitted into and detachably secured to the frame, whereby the width of the machine is varied, substantially as herein described.

2. In an orchard and vineyard cultivator, the frame having the fixed teeth, in combination with the independent or supplementary teeth having shanks adapted to be fitted into and detachably secured to the sides of the frame to vary the width of the machine, substantially as herein described.

3. In an orchard and vineyard cultivator, the cross plates of the frame having the grooved castings bolted between their ends, in combination with the supplementary attachable and detachable teeth having shanks fitted to the grooved castings, and the set-screws for holding said shanks, substantially as herein described.

4. In an orchard and vineyard cultivator, the main frame, consisting of the parallel 1ongitudinal body-bars, the cross-plates, between which the rear ends of the body-bars are bolted, and the parallel back bars bolted to the cross plates outside of the planes of the body-bars and within the planes of the ends of the crossplates, substantially as herein described.

5. In an orchard and vineyard cultivator, the main frame consisting of the parallel 1ongitudinal body-bars, the cross-plates connecting their forward ends, and cross-plates connecting their centers, the cross-plates,between which the rear ends ofthe body-bars are bolted, and the parallel back bars bolted to said crossplates outside of the planes of the bodybars and within the planes of the ends of said crossplates, substantially as herein described.

6. In an orchard and vineyard cultivator, the single casting serving as a hub or dust cap or cover for the wheel and as a support for the wheel-scraper, substantially as herein described.

In witness whereof I have hereunto set my hand.

GUY \V. CAMPBELL.
